— Dark Horse Comics website description[1]


Sonic the Hedgehog Encyclo-speed-ia documents a large number Sonic the Hedgehog games released over the series' history up until 2020. Each chapter dedicated to a game features a description of the game and a summary of its plot (if present), and features sub-sections that list levels, items, enemies and which levels they are associated with, bosses, and descriptions of any characters that debuted in their corresponding games. Also documented on the pages are "factoids" that describe canonicity information, cut content, localisation differences and other miscellaneous trivia. While the book documents each major game in release order, some spinoff games are grouped into their own dedicated sections, such as arcade games, edutainment games and mobile games.

The book also provides new English names for enemies and bosses that were never given an English name before or weren't named at all, such as the names for most of the bosses in the original Sonic the Hedgehog or the previously unnamed enemies that appeared in Chaotix.

The book also opens with an introduction written by Takashi Iizuka.

List of chapters


At the end of the book is a timeline of almost every known Sonic game released from 1991 to 2020, including games which do not feature in the book. The games mentioned only in this section are as follows:


Sonic the Hedgehog Encyclo-speed-ia makes several incorrect statements and printing errors. The following is a list of known errors and the chapters and pages they can be found on:

Chapter Page(s) Description
Sonic the Hedgehog (16-bit) 8 The factoid section states that Sonic was supposed to be "part of the band!". The section meant to say "part of a band!".
Sonic the Hedgehog (16-bit) 9 "Bridge" is misspelled as "brdige" in the description for Spring Yard Zone.
Sonic the Hedgehog (16-bit) 12 The description for the Orbinaut seems to have been mistakenly copied from the description for Crabmeat.
Sonic Arcade Classics 16 The overview for Waku Waku Sonic Patrol Car states that "Players sit insidean arcade cabinet shaped like Sonic's patrol car". This is meant to say "Players sit inside an arcade cabinet shaped like Sonic's patrol car".
Sonic the Hedgehog 2 (16-bit) 22 The overview states that "The Special Stage can now be accessed via the Star Post checkpoints with twenty rings", this information is slightly inaccurate as the Ring requirement is actually fifty.
Sonic the Hedgehog 2 (16-bit) 23 Four screenshots are used to represent Emerald Hill Zone. The first screenshot is erroneously a screenshot of Green Hill Zone.
Sonic the Hedgehog 2 (16-bit) 25 Grabber's sprite is missing its winch and its front set of legs.
Sonic the Hedgehog 2 (16-bit) 27 The artwork used for Micky is actually fanart drawn by former DeviantArt user RickyOwl (whose account was deactivated long before the book's announcement). A comment below Micky erroneously states the animal debuted in the restored Hidden Palace Zone in 2013 when it had always appeared in Mystic Cave Zone in the original game.
Sonic CD 34 A factoids section states "Wait too long, and Sonic will say, "I'm outer [sic] here!" He'll then jump off the stage, costing you a life.". This actually causes an instant Game Over, however it did cost a life in earlier prototype builds.
Sonic Chaos 36 The overview section for Sonic Chaos states that the player has to make their way to the end of an Act with 100 Rings to access the game's Special Stages. In the actual game, this isn't the case as the player is automatically warped to the Special Stage immediately after collecting 100 Rings.
Sonic Chaos 37 The entry for Mecha Green Hill Zone in Sonic Chaos' Zones section states that Eggman has "completely converted the Green Hill Zone of Sonic the Hedgehog 2 (8-bit)." The stage in the latter game was actually called "Green Hills Zone".
Dr. Robotnik's Mean Bean Machine 41 Though this page and the preceding page covers Dr. Robotnik's Mean Bean Machine, the name "Dr. Eggman" is incorrectly used instead of "Dr. Robotnik" in the description for Scenario Mode.
Sonic the Hedgehog 3 48 The story summary for Sonic the Hedgehog 3 claims that Super Sonic defeated Dr. Eggman in Sonic the Hedgehog 2. While the player can have all the Chaos Emeralds by the time they reach Death Egg Zone, Super Sonic cannot be used there without edit mode since the Zone doesn't have any Rings. Although, Super Sonic does appear in the good ending.
Sonic the Hedgehog 3 49 The description for Angel Island Zone states "A carpet-bombing by the Flying Battery sets the second act ablaze" when it is actually set ablaze in the first act by a swarm of Fire Breath badniks.
Sonic the Hedgehog 3 53 There are screenshots depicting Green Hill Zone, Mushroom Hill Zone and Death Egg Zone, neither of which are from Sonic the Hedgehog 3 but instead are from Sonic the Hedgehog and Sonic & Knuckles respectively.
Sonic & Knuckles 55 While each Zone featured in Sonic the Hedgehog 3 and Sonic & Knuckles shows at least one screenshot from each Act, Lava Reef Zone only features two screenshots both from Act 1. Act 2 is not shown.
Sonic the Hedgehog Triple Trouble 61-63 All instances of Meta Junglira Zone are incorrectly named "Meta Jungura Zone".
Knuckles' Chaotix 69 One of the screenshots used to represent Marina Madness is actually from Techno Tower.
Knuckles' Chaotix 73 A factoids section claims that Amy Rose was "supposed to appear in a scrapped Sound Test Mode in other leaked early versions.". Amy is still in the final game and can be seen via a cheat code in the color test.
Tails Adventure 76 The title screenshot for Tails Adventures is actually a rip of the title screen graphics by The Spriters Resource user DogToon64[6].
Tails Adventure 77 The first screenshot for Volcanic Tunnel incorrectly shows the opening cutscene.
Tails Adventure 77 The first screenshot for Cavern Island incorrectly shows Volcanic Tunnel.
Tails Adventure 79 The Jumping Combatants are listed twice in the enemies list for Tails Adventures. The second entry names them "Jumping Soldiers" and lists them to appear in Polly Mt. 2, though they actually appear in Polly Mt. 1. Their first entry claims they also appear in Lake Rocky, but they do not appear in that level.
Tails Adventure 79 The Robo Kukku is incorrectly associated with Battle Fortress 1 when they are actually exclusive to Battle Fortress 2.
Adventures with Sonic 98 The description for Twinkle Circuit claims that Sonic must play through it before accessing Twinkle Park. However, Twinkle Circuit is completely optional, even for Sonic. The description may be referring to the bumper car section of Twinkle Park rather than Twinkle Circuit itself.
Sonic Adventure 2 / Sonic Adventure 2: Battle 118 A factoid section states that out of the menu themes released for Sonic Adventure 2, only Dr. Eggman, Amy and Maria's themes were released in Japan. While this statement is correct for Amy and Maria's themes, Eggman's theme was also released in the West, and Shadow, Omochao, and the Secretary's themes (which were also Japan-exclusive) are not mentioned.
Sonic Advance 120 A volume bar is overlapping the top-left corner of the title screenshot for Sonic Advance.
Sonic Advance 121 While Egg Rocket Zone and Cosmic Angel Zone are listed separately, the second screenshot that represents Egg Rocket Zone depicts Cosmic Angel Zone.
Sonic Advance 2 125 Screenshots of Ice Mountain Zone from Sonic Advance are erroneously used to represent Ice Paradise in Sonic Advance 2.
Sonic Advance 2 128 Madillo's sprite is incorrectly cropped, showing loose pixels from another of Madillo's poses on the right of the sprite.
Sonic Heroes 131 Two of the screenshots representing Sea Gate are taken from a fan-made port of the level in Sonic the Hedgehog (2006). Part of the HUD and an Egg Gunner can be seen in the screenshots, and Amy is on her own.
Sonic Battle 142 The descriptions for Soniclash! and Tails' Fly & Get claim four Game Paks are needed to play. All mini-games in Sonic Battle only need one Game Pak.
Sonic Battle 143 The Shadow's Speed Demon mini-game in Sonic Battle is incorrectly named "Sea Gate".
Sonic the Hedgehog (2006) 163 Radical Train is misspelled as "Radial Train" in the description for Soleanna New City.
Sonic Riders 169 Space Theater is incorrectly named "Theater" in the list of battle stages.
Sonic Riders 171 The E-10000 series introduced in this game are mistakenly referred to as the "E-1000" series.
Sonic and the Secret Rings 183 King Shahryar is claimed to mistake Sonic for the Ma Djinn forces of Erazor Djinn. He does not do that - he instead finds Sonic insolent.
Sonic Rush Adventure 185 Blizzard Peaks is spelled without its plural as "Blizzard Peak".
Sonic Rush Adventure 187 All enemies that appear in Blizzard Peaks (the Crystal Head, Kaizoku Glider and Kaizoku Snowball) are incorrectly associated with Haunted Ship.
Sonic Chronicles: The Dark Brotherhood 207 The plot synopsis for Chapter 1 states that Tails arrives in Green Hill to inform Sonic of Knuckles being kidnapped. In the game, this doesn't happen as Sonic is the one to arrive in Green Hill while Tails contacts Sonic from Central City via remote radio.
Sonic Chronicles: The Dark Brotherhood 209 E-123 Omega's description for Sonic Chronicles: The Dark Brotherhood claims the player must recover his dismembered pieces so that he may join the party. This is incorrect, as the player doesn't need to look for his pieces for Tails to reassemble him.
Sonic and the Black Knight 213 The "Everything Is Canon" factoid claims that Sir Lancelot comments on the boss of Dragon's Lair resembling the Biolizard from Sonic Adventure 2. It is not Sir Lancelot who makes that comment, but rather Sonic.
Racing with Sonic 226 The Blue Cube is incorrectly named the "Blue Block" for Team Sonic Racing. It is named correctly in the Sonic Colours section, however.
Sonic Mania 254 A sprite of Scarab is incorrectly used for Icebomba.
Sonic Mania 257 Heavy Rider is referred to as male when she was described as female in the digital manualMedia:SM PC DIGITAL MANUAL UK V10 LR.pdf[7].
Sonic Mania 257 There is a missing space between "aspirations of" in Heavy King's description.
Olympic Games Series 271 The Dream Events section for the Olympic Games series claims the first game in the series, Mario & Sonic at the Olympic Games, did not feature Dream Events. The game did feature Dream Events, however they were not set in any specific location from the Sonic or Mario universes.
Olympic Games Series 271 Despite the above error, the screenshot used to depict the Dream Fencing event from Mario & Sonic at the London 2012 Olympic Games is ironically a screenshot of the very same event from Mario & Sonic at the Olympic Games.
Olympic Games Series 271 In the same section, the screenshot used to represent Dream Snowboard Cross in Mario & Sonic at the Olympic Winter Games is instead of the standard Snowboard Cross event.
Olympic Games Series 271 The entry for Hole-in-One Curling from Mario & Sonic at the Sochi 2014 Olympic Winter Games lists its inspiration and origin under Green Hill Zone from Sonic the Hedgehog. The event is actually based on its incarnation from Sonic Generations.
Super Smash Bros. Series 277 The list of unlock requirements for Sonic in the Super Smash Bros. series jokes that "defeating ten enemies in Cruel Melee in Super Smash Bros. Melee is not one of them", referencing Electronic Gaming Monthly's infamous April Fools hoax from their April 2002 issue, however the hoax claimed the player needed to defeat 20 enemies in Cruel Melee[8].
